VEN TILATING APPARATUS.

Application filed April 8,

My invention relates to the art of ventilating, lbeing more particularly a ventilating apparatus for removing gases and odors from a toilet bowl to an outlet exterior of the room whereby the room is freed of such gases and odors.

The principal object of my invention is to provide an apparatus of the class described of simple form and construction which may be readily attached to common forms of toilet bowls with a minimum amount of labor and cost.

Another object of my invention is Yto provide an apparatus of the character described which is connected to the lid common to toilet bowls whereby the Ventilating appa` ratus is placed in operation upon raising the lid, such operation continuing until the lid is again placed in lowered position.

Other objects and advantages will appear hereinafter from the following description and drawings.

Referring to the drawings, which are for illustrative purposes only,

Fig. 1 is a side elevation of a toilet bowl and ttings having mounted thereon a ventilating apparatus embodying a form of my invention, a portion of the bowl being broken away to better illustrate such apparatus.

Fig. 2 is an enlarged vertical sectional view of the Ventilating apparatus showing the manner of supporting the same.

Fig. 3 is a vertical sectional view on line 3-3 of Fig. 2.

Fig. 4 is a face view, partly in section, of the motor.

Fig. 5 is a sectional view on line 5 5 of Fig. 2, and

Fig. 6 is an enlarged vertical sectional view of the waste pipe and supporting members of the Ventilating apparatus.`

10 indicates a common form of Vtoilet bowl having a seat 11 and lid 12. such lid being hinged as indicated at 13. 14 indicates a flush tank, having a water supply pipe 15 and a discharge or iush pipe 16 which consists of a vertical leg 17 terminating in a horizontal extension 18 which discharges into the bowl in any well known manner.

The Ventilating apparatus consists essentially of a motor 20, a suction fan 21 and attaching or supporting means 22.

The gases from the bowl are .drawn through an exhaust conduit which consists of a hood 23 which extends downwardlv i926. serial No. 100,728.

into the upper portion of the bowl 10 being shaped to substantially fit the rear upper' portion of the bowl. The hood is formed with a neck 24 which lays fiat upon the upper portion of the bowl as shown in Fig. 1, such neck portion being connected by means of a flexible tube 25 with the intake opening 26 of the fan housing 27. At the intake opening 26 the fan housing is provided with a spider 28, the end-s of the legs of the spider being bent circumferentially as indicated at 29 to form a support for the tube 25, the spider also forming a` support for a bearing member 30 in which is threaded screw 31 which receives the end of a shaft 32. The shaft 32 supports a sleeve 33 fixed thereto, upon which is mounted in fixed relation thereto the fan element 21 of the suction fan. This fan element consists of two circular plates 35 which support therebetween the fan blades 36, the fan element being enclosed in the housing 27 by means of a plate 37 having a flange 38 which iits within a circular flange 39 formed as part of the fan housing.

The motor 20 consists of a rotor comprising a hollow cylindrical member 40 mounted and secured to, in any suitable manner, the inner end of the shaft 32, the chamber in the member 40 communicating with a hollow spindle 41 formed on the rotor, which spindle is mounted to rotate in a hollow stud or boss 42 formed on the motor casing 43, such casing being secured in any suitable manner to the side of the plate 37 of the fan housing.

The opening in the boss 42 communicates n with a ipe 45, controlled by a valve 46, connecte to the tank water supply pipe 15 whereby water under pressure is delivered to the rotor member 40 and discharged therefrom through orifices 48 into the motor housing from whence it is ldischarged through an outlet pipe 49 into the flush pipe 16.

The ventilating apparatus is primarily supported on' the flush pipe 16 by means of a clamping member consisting of upper and lower straps 50 and 51 respectively which extend around the pipe 16 being clamped thereon by means of bolts 52. The upper strap member 50 is formed with a dome or hollow extension 53 which engages a rubber gasket 54 around the pipe 49 thereby forming a water-tight joint around the pipe 49 as it enters the Hush pipe 16. This construction just described supports the pipe 49 which in turn supports the Ventilatingl apparatus in View of the Connection of the pipe 49 to the motor housing which may be of any permanent character.

The valve 46 and consequently the operation of the motor and suction fan is controlled by a link 56 pivotally connected to the lid 12 of the closet so that when the lid i, is raised the Valve L16 is opened and the connected to said bowl, a Ventilating apparatus comprising a conduitor exhausting gases from said bowl, a suctionY fan at the outer end of said conduit, an exhaust outlet pipe for said fan, a sha-it for said fan, a rotor mounted on said shaft, a water supply pipe' for said rotor, a valve in said water supply pipe, a casing enclosing .said rotor, a discharge pipe for said casing Vconnected into the Hush pipe of said bowl, a gasket on said dischrrg'e pipe, means 'for clamping said discharge pipe to said'flush pipe, Vsaid clamping means engaging said gasket to forni a writer-tight joint between said discharge pipe. and said flush pipe, and means whereby said valve is eonneeted to said lid whereby raising said lid operates said valve to deliver water to said rotor. y

in testimony whereof, l har'e hereunto set my hand at Los ,fi-ingeles, Calif-erina,` this 19th day oi March, 1926.
